That's about Max for a full moon near the equator twice a year.

Anything less should be well below the trigger level for phytochrome conversion and will not mess with the photoperiodicity.

Got new neighbors next door and their porch light worried me.
As did the hellishly bright seeming streetlights from 2 other directions.
Hadda get a good Luxmeter anyway for my led work so I whipped it out before hassling the new neighbor.

Here's what I found.
The porchlight was 0.1 Lux by the time it reaches my girls.
So, no gotta bug nobody.
The streetlights from 2 other directions max at 0.2 Lux.

3 less things to worry about, yah? :jointsmile:

That's my story and ya'd have to bribe me off it.

This is a very good info you gave us Weezard. I approve!
I have some plants on balcony with full of street lights around + light from my window. No hermies at all. All were fine.
Maybe the plants which are don't know what is the total darkness, they're adapting to live with a little light at night?

I had hermies with my current grow, they effected only from where the light leak was. Male flowers were only on those branches. Rest of the other branches are perfect female. Maybe yours were like that too?
